City planner asks Sandpoint sustainability panel to define sustainability criteria for PUD density bonuses

Sandpoint — City Planner Bill Dean asked the Sandpoint Sustainability Committee on Aug. 26 to identify sustainability measures the city could require or incentivize when developers seek density increases through planned unit developments, or PUDs.

“The code is kind of a complicated ordinance. It’s big and clunky, and there’s lots to it,” Dean told the committee, referring to the city’s Title 10 zoning code and its PUD provisions. He said council asked staff to tighten ambiguous language in the PUD rules — including how and when density bonuses are awarded — and to clarify expiration and extension procedures for stalled projects.

Dean described the current PUD formula in which the code allows up to a 40% density increase broken into roughly 10% increments tied to items such as improved landscaping, site planning and “affordable housing as defined by council.” He said the ordinance does not specify objective criteria for those 10% bonuses and that staff and the planning commission want clearer, measurable standards.

Why it matters: PUDs are the city’s tool for allowing development that departs from base zoning in exchange for public benefits, and changes to the PUD rules could affect the size, location and environmental footprint of new housing. Dean said at least one developer has sought density increases to make smaller, more affordable housing viable; he and planning commissioners want guidance from the sustainability committee on which environmental or design measures should count toward a bonus.

Committee members and staff suggested a range of options for measurable incentives and minimum expectations. Stormwater treatment and on‑site retention, greater use of permeable surfaces, and measures to reduce heat‑island effect — such as required tree canopy or shading percentages — were raised repeatedly. Committee members also proposed stronger dark‑sky lighting standards for PUD projects and higher exterior‑lighting performance than the city’s current code.

Energy and building standards drew discussion as well. Dean described options that could be written into the PUD rules or used as criteria: solar readiness and building orientation, stronger insulating and window (U‑value) standards, and explicit adoption or reference to green‑building frameworks such as LEED or locally tailored “LEED‑equivalent” benchmarks. One example discussed: a density bonus if a specified share of homes in a PUD achieve LEED Silver (or equivalent) certification — noting that certification carries cost and therefore affects affordability.

Several committee members urged that incentives not unintentionally raise housing costs. Dean acknowledged the tension between requiring higher performance and preserving affordability; he suggested the committee weigh tradeoffs and propose measurable, attainable standards that can be documented in permit applications.

The committee also discussed land‑use mechanics and implementation limits. Dean said the city’s draft revisions will need legal and procedural polish; he offered to draft candidate language and return with concrete proposals. He asked the committee to return a short, plain‑language sentence or two describing what “counts” as sustainability so staff can convert it into code text.

Other ideas offered by members included incentivizing smaller home footprints and townhomes; quantifying open‑space percentages within a development; retention of native vegetation; community gardens and composting; and exploring reuse or deconstruction standards for building materials where feasible. Members suggested outreach to nearby university programs (University of Idaho and regional schools were named) for student project support, and to use GIS mapping to target likely PUD areas such as parts of Boyer and downtown.

Dean stressed process limits: larger stormwater system upgrades and citywide policy changes will need separate, broader actions; PUD criteria could encourage above‑and‑beyond measures for individual projects but are not a substitute for systemwide infrastructure work.

Votes at a glance - Approval of minutes from the June 24, 2025 meeting — motion and second recorded; outcome: approved. - Motion to amend the agenda to add additional presentations by committee members — motion approved. - Election of vice chair — Deborah Dickerson was nominated and elected vice chair; motion passed. - Attempted nomination for board chair (nomination of Christine Moon) — the nomination process as recorded in the meeting transcript did not result in a successful, finalized motion (motion did not pass as recorded in the transcript).

What’s next: Dean said he will draft proposed code language and a short plain‑language statement of sustainability priorities for the committee to review; committee members agreed to provide feedback by email to the clerk so the group does not run afoul of public‑meeting rules. The committee also agreed to pursue partner options with regional university programs and to consider a visible, near‑term project (members suggested sustainable landscaping and tree/median plantings) as an early “low‑hanging fruit” implementation.

Quotes “Title 10 establishes the PUD ordinance. It’s kind of a complicated ordinance. It’s big and clunky, and there’s lots to it,” Bill Dean, City Planner, said while explaining the code changes staff proposes.

“We have a number of issues in this town. Stormwater is definitely an issue…you can do retention basins and things like that just to keep the stormwater on‑site,” a committee member said during discussion of suggested measures.

“We could give you a 10% density bonus if 50% of your homes are LEED silver or gold, or where you pick your number,” Bill Dean said, noting certification costs and tradeoffs with affordability.

Ending The committee asked staff for a brief draft the panel could comment on at its next meeting; members also volunteered to research model sustainability plans and university programs that might partner on an energy audit or student projects. Committee leaders said they hope to prioritize one visible, achievable project within a year while the longer code changes move through planning commission and council review.
